IMPROVEMENT I N ATTACHMENTS FOR WASTE-PIPES.

Specification forming part of Letters Patent No. 214,982, dated May 6, 1879; application filed March 17, 1879.

To all whom it may concern:

Be it known that I, HENRY W. ATWATER, of Newton, in the county of Middlesex and State of Massachusetts, have invented an Improved Attachment for Waste Pipes from Wash-Bowls, Bath-Tubs, and the like, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, making a part hereof.

The object of: my invention is to guard effectually against the stoppage of waste-pipes by lint, hair, 850.; and it is an improvement on the invention described in my Patent No. 157,957, dated December 22, 1874.

In the drawings, Figure 1 shows the method of applying my attachment, part of the wastepipe being broken away to show the perforated cylinder. Fig. 2 shows my attachment in section. The other figures show details.

A indicates a wash-bowl or other receptacle for water. 13 B is the outlet-pipe, secured in the bottom of A. G is a hollow cylinder, perforated, as shown, slightly conical at c, to fit the slightly-conical part of the opening B the two being ground together to make a water-tight joint, and yet allow the cylinder 0 to be readily removed from B. The plug or stop- This device is shown in Figs. 3 and 4. When the water does not flow freely the rod 0 with its disk 0 also the cylinder 0, should be removed, which is readily done by means of the key 0, as indicated in Figs. 3 and 5, and cleaned.

The body of the cylinder 0 should always be somewhat smaller than the part of the outlet-pipe around it, thus forming a chamber between the outlet-pipe and the cylinder, so that when the cylinder is clean the water will pass freely through the perforations in the side of the cylinder, as well as those in the bottom.

It will be seen that my device is very si1nple, and is readily applied to any wash-bowl. As the cylinder G is not fastened to the wastepipe and does not assist in attaching the waste-pipe to the bowl, it is easily removed, and being surrounded by a small chamber, the water always has a free passage into the wastepipe, unless, of course, all theperforations in the cylinder are stopped up.

What I claim as my invention is- 1. In combination, the outlet-pipe B B and the perforated cylinder 0, arranged together as and for the purpose specified.

2. In combination, the perforated cylinder 0 and the rod 0 with its disk 0 as set forth.

H. WILLIAM ATWATER.
